Y is a 8 threshold detector input channel. Channels 0..7, 8..15, 16..23 9 and 24..31 has common sensor types. 10 11What: /sys/bus/iio/devices/iio:deviceX/events/in_voltageY_thresh_falling_value 12Date: August 2015 13KernelVersion: 4.2.0 14Contact: source@cogentembedded.com 15Description: 16 Channel Y low voltage threshold. If sensor input voltage goes lower then 17 this value then the threshold falling event is pushed. 18 Depending on in_voltageY_sensing_mode the low voltage threshold 19 is separately set for "GND-Open" and "Supply-Open" modes. 20 Channels 0..31 have common low threshold values, but could have different 21 sensing_modes. 22 The low voltage threshold range is between 2..21V. 23 Hysteresis between low and high thresholds can not be lower then 2 and 24 can not be odd. 25 If falling threshold results hysteresis to odd value then rising 26 threshold is automatically subtracted by one. 27 28What: /sys/bus/iio/devices/iio:deviceX/events/in_voltageY_thresh_rising_value 29Date: August 2015 30KernelVersion: 4.2.0 31Contact: source@cogentembedded.com 32Description: 33 Channel Y high voltage threshold. If sensor input voltage goes higher then 34 this value then the threshold rising event is pushed. 35 Depending on in_voltageY_sensing_mode the high voltage threshold 36 is separately set for "GND-Open" and "Supply-Open" modes. 37 Channels 0..31 have common high threshold values, but could have different 38 sensing_modes. 39 The high voltage threshold range is between 3..22V. 40 Hysteresis between low and high thresholds can not be lower then 2 and 41 can not be odd. 42 If rising threshold results hysteresis to odd value then falling 43 threshold is automatically appended by one. 44
